The standard error of the difference of sample means is 0.444
From the complete question, we have the following parameters
<u>Canadians</u>
- Sample size = 50
- Mean = 4.6
- Standard deviation = 2.9
<u>Americans</u>
- Sample size = 60
- Mean = 5.2
- Standard deviation = 1.3
The standard error of a sample is the quotient of the standard deviation and the square root of the sample size.
This is represented as:

The standard error of the Canadian sample is:

So, we have:

The standard error of the American sample is:

So, we have:

The standard error of the difference of sample means is then calculated as:

This gives


Take square roots

Hence, the standard error of the difference of sample means is 0.444

The frame rate of a virtual reality (VR) headset indicates: the number of images displayed per second.
<h3>What is Virtual Reality (VR) headset?</h3>
A virtual reality (VR) headset refers to a head-mounted device which consist of two LCD displays (one per eye) that provides the wearer with a view of virtual physical environments (realities) and human-machine interactions through the use of various computer technologies.
<h3>What is frame rate?</h3>
Frame rate can be defined as a a measurement of the speed at which successive images are displayed per unit of time (second).
In this context, the frame rate of a virtual reality (VR) headset indicates the number of images that are displayed per second such as <u>24 fps</u>.
